The trial was conducted in the village Alokdiar of Shajadpur upazilla under Sirajgonj district. Twenty crossbred lactating dairy cows of 320 ±15.5 kg live weight were used for the trial. Animals were equally and randomly allocated into four groups, T<sub>0</sub> (Napier+concentrate), T<sub>1</sub> (Napier+concentrate+100g DCP), T<sub>2</sub> (Napier+concentrate+150g DCP) and T<sub>3</sub> (Napier+concentrate+200g DCP). Total DMI did not differ significantly (p&gt;0.05) among the groups but highly significant differences (p&lt;0.01) were found in Ca intake. Ca balance; and Ca in feces, Ca in urine, Ca in milk and total Ca excretion differed significantly (p&lt;0.05). No significant  difference (p&gt;0.05) was found in DM in feces (%), DM in feces (kg/d) and milk production (L) among the treatment groups except urine excretion. There was a linear increase of body condition score (BCS) with DCP (T<sub>1</sub>, T<sub>2</sub> and T<sub>3</sub>), but BCS was linearly declined in non DCP diet (T<sub>0</sub>). Diets with 150g DCP may be suggested for optimizing Calcium balance and body condition score of dairy cows fed Napier grasses.</p><p>DOI: <a href="http://dx.doi.org/10.3329/bjas.v43i3.21648">http://dx.doi.org/10.3329/bjas.v43i3.21648</a></p> <em>Bang.
